Economic and ecological aspects are increasingly leading to a move away from bagged and small packaged goods and towards larger type of packaging, such as BigBags, containers etc. TOP TRAC was specially developed for performing controlled removal from these types of large packagings. The components to be removed are sucked upwards to the scales based on the exact formula, in precise dosages, dust-free, in layers and practically free of segregation.
TOP TRAC is travels fully automatically over rails from container to container with millimetre precision, day and night and without the need for any personnel! The system can also be connected directly to a silo system that is being operated as a part of the suction conveyance process.


  • Equipment for lifting containers is no longer need. A pallet truck sufficed for loading the pallets and BigBags.
  • Easy replacement of the containers.
  • 8 container positions in the standard version. Extension positions can be retrofitted easily and with little extra effort.
  • No pollution of the environment and surroundings, all operations take place dust-free.
